NEET Biology question
Which of the following is the right statement? I. Angiotensin-II, being a powerful vasoconstrictor, increases glomerular pressure and thereby GFR II. Angiotensin-II activates the adrenal cortex to release aldosterone III. Aldosterone promotes reabsorption of Na⁺ and water from the DCT and CT, leading to an increase in GBP and GFR IV. ANF causes vasoconstriction Select the right combination.
Answer: (A)
Solution
Angiotensin-II does act as a vasoconstrictor that raises glomerular blood pressure and GFR (I, true), it activates the adrenal cortex to release aldosterone (II, true), and aldosterone promotes Na⁺/water
